Default Re: Ferranti TC1004. Baptism of fire.

WOW! That is a really bad example of a broken down Ekco case second only to a similar one I've just rebuilt for an Ekco TMB272. Good news is the windings will be OK.
I doubt if the metal rectifier is faulty. I repaired countless numbers of Ekco receivers and never once replaced the rectifier. It is made by AUTOMAT, incredibly reliable. Ekco and other makers that had previously used he U801 valve needed something reliable to replace it.
I would suggest you make up a new case and give it a try. The line output stage is probably heavily loaded due to case breakdown as was the TMB272. Regards, John.
